A new data on the age of kimberlites from the Yakutian diamondiferous province, Russia

Using Rb-Sr isochronous method the age of five kimberlite bodies (pipes) of Yakutian diamondiferous province is determined. As found, the age of recently discovered Nakyn field corresponds to the Middle Paleozoic cycle of kimberlite magmatism activity at Siberian platform. The data for Nakyn field together with the obtained age for the Komsomolskaya pipe and previously reported data represent the significant argument confirming formation of all industrially important diamondiferous deposits of Yakutian province within the integral cycle of kimberlite magmatism activity.
